New STN® Breaks Ground with Markush Structure Search and Enhanced Content for Intellectual Property Exploration and Research

Chemical Abstracts Service (CAS) and FIZ Karlsruhe are delighted to reveal the latest innovations for Intellectual Property (IP) professionals. New STN, a web-based search solution, offers access to essential, curated content in an intuitive interface designed for professional IP searching. Highlights of this most recent release include Markush structure search, additional databases, more export formats and numerous workflow and interface enhancements.

As the number of chemical structures disclosed in patents rapidly increases, it is imperative that IP professionals have the right tools for searching this information efficiently and reliably. The latest release of new STN introduces Markush structure search with delivery of MARPAT® from CAS. Combined with CAS REGISTRY? and Derwent Chemical Resource (DCR), new STN provides unsurpassed coverage of generic and exemplified chemical structures.

“Markush search is a necessary feature for anyone searching chemical patents,” said Matthew McBride, Manager, Science IP. “With new STN, I can simultaneously search a single chemical structure across key substance databases, saving time and ensuring my confidence in the results.”

In addition to Markush search capabilities, the latest release includes highly requested engineering, petroleum and energy databases COMPENDEX, INSPEC®, TULSA, ENCOMPLIT and ENCOMPPAT, as well as ReaxysFile™ for chemical substance information and associated references for patent-related searching. The Cooperative Patent Classification (CPC) and International Patent Classification (IPC) thesauri are also available to help users more easily incorporate classification codes into their search strategies.

“Now with 30 databases covering a broad spectrum of science and technology, IP professionals in many disciplines can take advantage of the robust capabilities of the new platform to transform the way they conduct intellectual property searches,” said Dr. Rainer Stuike-Prill, vice president marketing and sales at FIZ Karlsruhe.
The latest release demonstrates the continuing importance of customer feedback in extending functionality and enhancing operational efficiency. An updated structure editor allows searchers to model structures from CAS Registry Numbers®, and new single-click controls simplify cross-file searching between databases. The latest release also supports exporting search results in XML and BizInt file formats, enabling searchers to more flexibly share, analyze and report search results.

“New STN delivers the high-quality information and search power organizations around the world need to protect their valuable intellectual property,” said Christine McCue, CAS vice president marketing. “With this release, we are excited to offer unique capabilities and enhancements, like Markush structure search and new export options that make intellectual property more discoverable and help our customers derive the insight and intelligence that drives the success of their businesses.”
